This is the first in our bridge series although a bridge is not the first thing you think of when you talk about Steel Buildings it is one of the first things you think about when you talk about Steel Structures, and although most bridges are not made mostly of steel, they almost all use a significant amount of steel, either as cables or more commonly steel used in reinforcing concrete ,with out the Steel most large structures today could not be possible, so lets start the Bridge Series with the Bang Na Expressway
The Bang Na Expressway is a huge Conrete and Steel Bridge that streches 33.51 Miles to make it the longest Bridge in the world as of this posting.
